MoFi Electronics StudioDeck “The StudioDeck+ package really is that good, displaying an open, lucid style that's thoroughly addictive and an almost magical ability to make music come alive in a way only the best can.” — HI-FI CHOICE, GROUPTEST WINNER 2020 From the undisputed leader in audiophile recordings since 1977. Designed and made in the USA with the goal of vinyl playback that's faithful to the original master recording. The StudioDeck+ versions come with installed cartridges. The StudioDeck +M comes with the MoFi MasterTracker, and the +U comes with the UltraTracker. MasterTracker features a V-Twin dual-magnet generator that mirrors the layout of the cutting head that originally makes a record’s grooves. Employing two low-mass, powerful magnets aligned in a V formation parallel with the record grooves, MasterTracker accurately extracts music from your LPs and features stellar tracking ability. UltraTracker touts a "V-twin" dual-magnet generator comprised of two powerful magnets aligned in a formation parallel with the stereo record grooves. Developed in collaboration between Mobile Fidelity engineers and Spiral Groove founder Allen Perkins, UltraTracker extracts immense amounts of detail, dynamics, tone, and texture from LPs.
